Psyche is one of the richest anthropological terms in the New Testament, spanning the full range from physical life to the deepest interior of a person. Jesus teaches that one can lose one's psyche yet save it (Matt 16:25), playing on both the physical and spiritual dimensions simultaneously. The word renders Hebrew nephesh throughout the Septuagint, carrying forward that same broad semantic range. Spanish distinguishes 'alma' (soul) from 'vida' (life), French uses 'ame,' and German 'Seele,' but the Greek term intentionally holds both together. In most of its 103 New Testament occurrences, psyche refers to the inner self as the seat of emotions, will, and spiritual identity rather than mere biological existence.
